Package: openmpi-checkpoint
Version: 1.4.1-1
Severity: important
openmpi-checkpoint does not currently depend on blcr-util. However,
ompi-restart will segfault unless blcr-util (upstream bug maybe, I reported to
the OpenMPI users mailing list, still got no reply).
Although you can take checkpoints without blcr-util installed, restoring a
checkpoint with ompi-restart fails.
Due to bug #572021 that I also reported, you'll need to compile OpenMPI from
sources to verify this bug (or fix #572021 first):
1) Install openmpi-bin, openmpi-checkpoint (or compile OpenMPI from source, if
#572021 is not fixed yet), and make sure you don't have brcl-util installed.
2) Compile a simple MPI app (the typical "ring" app will do it).
3) Run it like this, for example:
modprobe blcr
mpirun -np 4 -am ft-enable-cr ./ring
4) Take a checkpoint, for example:
ompi-checkpoint --term <PID OF THE MPIRUN PROCESS>
5) Try to restore the checkpoint:
ompi-restart ompi-global-snapshot-<PID>.ckpt
The expected result would be having the ring app complete. Instead ompi-restart
(or one of its children, I'm not sure) segfaults.
Now install the package brcl-util and repeat this procedure. You'll see that
ompi-restart does not segfault. This indicates that openmpi-checkpoint should
depend on blcr-util.
Proposed fix: Add blcr-util to Depends.
Note that brcl-util provides binaries like cr_restore, cr_checkpoint, etc. One
would think ompi-checkpoint/ompi-restart uses only libcr directly, but that
doesn't seem to be the case for ompi-restart.
